Hyperlinked Graphic in an OWA Signature? Well Yes, As a Matter of Fact!

Roll up your sleeves, pour a cup of coffee or tea and let's zap OWA into submission. This little ditty not only allows you to insert a graphic into your OWA signature, it also hyperlinks that graphic to your web site -- and you won't have to rely on Outlook's
or OWA's "caveman-walking-around-in-animal-skins-primitive" signature editors to do this. Oh, this also includes your clickable email address as well.

To be sure, you are about to achieve a couple of things OWA was not designed to do; and trust me, if you are successful, you may very well become an IT Rock Star, even if your boss(es) don't realize it. Suddenly, you will also realize that you have pushed
Office Outlook beyond it's Microsoft design specification as well.

This has been tested and works great with OWA running through IE7 & IE8 for Windows XP, IE9 for Windows 7, IE10 for Windows 8 and is cross-browser compatible with Chrome24 and Firefox18 (both of which are the latest versions at this writing. It runs
on all 32-bit and 64-bit AMD and Intel PC desktops and laptops. This signature will be properly displayed in email sent to iPhones 3, 4, 4s & 5) and iPads (1, 2 & 3). The signature you create for OWA is also compatible with Outlook 2010
and backward-compatible with Outlook 2007 and 2003.

1.) Put your graphic file (.jpg, .gif, .png, or whatever) onto your web site (this will become externally referenced in the below HTML). If you have server-side control of your Exchange server, place your graphic there; otherwise, a safe, out-of-the-way
place on your web site will do -- and write down the path to this graphic.

And get this -- you can copy and paste the contents of an OWA email signature editor into any Outlook email signature editor, save it, test it, and thereby create or recreate any Outlook email signature, regardless of version.

P.S. I recently rolled out this solution for over 200 users working at a bank, so this isn't a hypothetical -- it's a very real, deployed solution.
